Reverse osmosis replacement filters original organic cellulose for 5 stage under sink brand name reverse osmosis system, 99.9% Reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water, reverse osmosis system schematic the main stage in this systems is the RO membrane and all of the other replacement filters are serving and providing protection to that membrane, if the pre-filters fail to work due to poor quality, that means your RO membrane will not give you 99.9% Reduction rate. it include 4 filters and a membrane that must be replaced periodically, The different filters represent the different stages that the water goes through while being purified, Generally - Pre-Filters and post-Filters in Reverse osmosis system can last around 8 To 12 months between changes.

Only the original organic RO membranes can last as long as 5 years
Stage 1-
Sediment filter is the first filter installed in reverse osmosis system 
The main function of a sediment filter is to remove large and fine particles from a drinking water, such as sand, dirt, silt, and rust particles. Removal of such particles allows for a better performance of all the following filters, such as carbon block or GAC filters.
Micron rating: 5 micron.
Dimensions: ( DXI 10 X 1/3 - 3/4") x 2.6"
Lifetime: please replace every year, depending on the water quality.

This filter is wrapped and sealed and meets NSF Standards and Regulations. Filter will fit any residential reverse osmosis unit that features standard 10” filter housing ( look for compatible systems list )

Stage 2-
activated carbon GAC filter are well-known for their highly efficient reduction of chlorine taste and odor branded for reverse osmosis system
Taste and odors of many organic chemicals and volatile organic compounds.
All GAC filters are made with organic high quality coconut shell carbon.
Micron rating: 5 Micron.
Dimensions: ( DXI 9 X 1/4 - 3/4") x 2.6"
Lifetime: please replace every year, depending on the water quality.

This filter is wrapped and sealed and meets NSF Standards and Regulations. Filter will fit any residential reverse smosis unit that features standard 9.8” filter housing ( look for compatible systems list )reverse osmosis system for well water

stage 3-
 Activated Carbon Block ,Filter are made of fine coconut shell carbon to remove odors and tastes of many organic compounds and chlorine especially.
Because this filters are made of a packed carbon (forming a cylinder block), they offer a much finer filtration of suspended particles and dirt.
Micron rating: 5 Micron.
Dimensions: ( DXI 9X") x 2.6"
Lifetime: please replace every year, depending on the water quality.

This filter is wrapped and sealed and meets NSF standards and regulations. Filter will fit any residential reverse osmosis unit that features standard 10” filter housing ( look for compatible systems list )

Stage 4-
Original organic aquasky ROT-4 - 50 GPD NSF certified thin film TFC Membrane is the main component of Aquasky rot-4 reverse osmosis unit.
Made with 100% Organic fine thin film flat sheet
99.9% reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water.
Only the original organic aquasky rot -4 membrane has The micron rating of a thin film less than 1/10000th of a Micron which is 620,000 times finer than A human hair, 2,500 times smaller than bacteria and 20 Times smaller than any virus. see reverse osmosis system installation diagram

Stage 5-
Original organic Inline carbon filter for aquasky rot-4 is known as polishing filters, because they would usually be the last stage of any standard reverse osmosis circuit.
Being made of high quality coconut shell carbon they stabilize the water tasting qualities and further remove any traces of bad tastes and odors.
Dimensions: 10.6 " x 3"
Lifetime: please replace ones in 1- 2 years.
